Push Button Fortune

They are commonly found in motel stairwells, and look virtually the same as normal lights. To my knowledge, they have been around for years.

To switch the light on, you push a button – the button goes in and stays there and the light turns on. As you walk down the stairs, the button slowly comes back out. When it has come fully out, the light turns off.

When they next person comes, they can push the button and the light will turn itself off after a certain time.

Do these lights have a special name?? What are they called??

It is not the lights that are special but the switch. Pneumatic time delay switch.

Here is an example of the type of switch….
